ATX 300 W power supply

This ATX-format unit delivers 300 W of continuous power for standard desktop builds. It suits office workstations, home PCs and light-gaming rigs that stay within modest power envelopes. The supply has been tested and confirmed working before dispatch.

300 W capacity and headroom

The 300 W rating covers typical mid-range CPUs and single-GPU configurations without supplemental connectors. Systems drawing sustained loads above 300 W or requiring multiple high-power graphics cards will exceed the available headroom.
